Streaker - The Green Diamond | VIM |

The Green Diamond of the Illinois Central Railroad.

It was the last streamliner built with the power car articulated with the train; future streamliners featured a matched but separable locomotive.

This train could be seen whizzing along at over 100 mph powered by a 600 hp spark ignition power plant (similar to an auto engine, but much bigger...) It represented the pinnacle of aerodynamic design for 1936.

I always thought the engine looked like it was scowling.
